Description

What this equipment is and what it's designed for.

By presenting the main challenges of a capsulorhexis scenario, the RHEXIS task allows users to learn, train and perfect the fine motor skills required to properly use the wound as a fulcrum point for instrument movement; a fundamental skill in ophthalmic surgery.

Recommended Holder: MINI-HOLDER and ROMANO

Features and what's included

What the equipment does and what comes in the box, as described by the manufacturer.

Features

Improve your control by creating a centered and circular rhexis (capsulorhexis scenario)
Intraocular instrument manouvering skills
Improve your technique by working through a fragile wound
Gain confidence and motion control as you decrease time to completion

Evaluate the task by reviewing the following parameters:

INCISION INTEGRITY: The integrity of the wound relates to good technique in manipulation of instruments through ports, a fundamental skill of ophthalmic surgery.Consistent rhexis size is an indicator of good technique and understanding of scale.
RHEXIS CENTRATION: Although an offset is sometimes desired (nasal and superior) in real cases, for the purposes of task training and evaluation, a centered rhexis is convenient for scoring with simple instrumentation. A centered rhexis shows control of the surgical landscape.
COMPLETION TIME: Although in real surgery situations quality is more important than speed, at a basic skill training level, time to completion is a good indicator of a learning curve. As familiarity with steps and confidence with the technique increases, a decrease in time to completion is expected.

SETUP WITH ORBIT HOLDER:

Insert the RHEXIS model in the ORBIT Model Eye Holder (compatible with BASIC-ORBIT and FLEX-ORBIT). Be careful not to damage delicate structures when inserting the models.
Use a broad-tip sharpie, to color the tip of a dry cotton swab; add a couple of water drops to the capsule and then gently remove the excess water with the stained swab. This will lubricate the model and lightly stain the capsule.
Make an incision on the limbus with your knife of choice. Entry depth, angle and incision width can be demonstrated and practiced. NOTE: The model promotes the user to create and work from a posterior incision.
Start a capsule tear with acystotome. NOTE: Make the flap broad so it is easy to grasp with the forceps. The capsule in the model is more fragile than the real capsule and requires a fuller bite with the forceps.
Manipulate the Utrata forceps of choice through the port to create a continuous circular tear on the capsule. NOTE: The model promotes frequent regrasping and gentle manipulation of the forceps. Breakage of the capsule flap can result if a long tear is attempted without regrasping. The capsule may be cut by the forcepsif the pinching force is too high.
